After care service

So I recently upgraded to a note 5 and 2 days after getting the phone I called all the Samsung stores closest to me to confirm if they had any stock of covers for the phone. Eastgate didn't have stock and referred me to rosebank which is quite a distance.I mistakenly dropped the phone and the back cover is badly damaged due to me not getting a Cover. After I dropped the phone I went to samsing Eastgate and guess what they had stock of different covers. Had to buy one for R500 and when asked about the cost and warranty about the back cover I was told.Samsung had no spares yet and the back cover is not covered warranty. This is quite disappointing as the back cover is now made of glass. Do I have to pay R2000 to fix this? This is not my only problem I've been enquiring about the wireless charger and flip covers and nobody has stock. The service from Samsung is shocking u keep on being referred from pillar to post yet I've been a loyal Samsung customer and a huge fan of the note series.
